What Makes Primary Care Billing Different, and Where Revenue Gets Missed
Primary care billing centers on evaluation and management, or E/M, coding for office visits, along with Annual Wellness Visits, preventive care, and referral coordination. Because most primary care revenue comes from E/M levels 99202 through 99215, small documentation gaps compound quickly across a high volume patient panel.
One of the biggest missed opportunities is HCPCS add-on code G2211, which pays for the added complexity of being a patient's ongoing, longitudinal point of care. CMS estimates G2211 will be submitted on roughly 90% of primary care E/M claims, yet many independent practices still are not billing it consistently on every eligible visit. The American Academy of Family Physicians notes that G2211 applies broadly to established patient relationships, and CMS confirms the rules directly in its official G2211 FAQ. Getting Annual Wellness Visit billing right matters just as much, since AWVs billed the same day as a problem focused E/M visit require modifier 25 and correct documentation to avoid denial. Strong coding support paired with clean claim submission is what keeps this revenue from quietly disappearing.
Every E/M visit is checked for G2211 eligibility before the claim is submitted.

Primary Care CPT and HCPCS Codes for 2026
A quick reference for the codes that drive most primary care billing. Rates are approximate national Medicare figures using the 2026 conversion factors of $33.40 (non-APM) and $33.57 (qualifying APM participants); commercial payer rates vary.
| Code | Service | Notes |
|---|---|---|
| 99202 to 99205 | New patient office or outpatient E/M visits, by complexity level | Varies by level |
| 99211 to 99215 | Established patient office or outpatient E/M visits, by complexity level | Varies by level |
| G2211 | Visit complexity add-on for longitudinal primary care relationships | ~$16 nationally |
| G0438 | Initial Medicare Annual Wellness Visit | Separately payable |
| G0439 | Subsequent Medicare Annual Wellness Visit | Separately payable |
| 99341 to 99350 | Home or residence E/M visits, now G2211 eligible starting 2026 | Varies by level and setting |
G2211 requires the underlying E/M base code and cannot be billed alone. Verify current payer specific rates and modifier 25 rules before submission.
Our Primary Care Billing Process, Step by Step
STEP 01
Encounter Documentation Review
Every visit note is reviewed to confirm the E/M level and check for G2211 eligibility based on the patient relationship.
STEP 02
E/M Leveling and Coding
CPT codes are assigned based on documented complexity, avoiding both undercoding and overcoding.
STEP 03
Preventive Service Coordination
Annual Wellness Visits and same-day E/M services are coded together correctly, with modifier 25 applied when required.
STEP 04
Claim Submission and Follow-Up
Clean claims are submitted daily, and any denial is worked promptly rather than written off.

Figures represent industry-standard benchmark ranges, not a guarantee. Actual results vary by payer mix, documentation quality, and patient panel.
Generalist Billing Staff vs a Primary Care Billing Specialist
G2211 alone is new enough that most in-house billing teams have not built it into their routine workflow yet.
Generalist Billing Staff
- G2211 rarely billed consistently, even on eligible visits
- AWV and same-day E/M visits occasionally miss required modifiers
- E/M levels assigned quickly without a documentation cross-check
- Limited bandwidth to track new PFS updates like the 2026 G2211 expansion
ClaraRCM Primary Care Billing
- G2211 eligibility checked and applied on every qualifying encounter
- AWV and same-day E/M visits coded with correct modifier 25 usage
- Every E/M level reviewed against documentation before submission
- Coding workflow updated as soon as new PFS rules take effect

Common Questions About Primary Care Billing
What is primary care billing?
Primary care billing covers coding and claims for office visits, Annual Wellness Visits, preventive care, and referral coordination, centered mostly on evaluation and management, or E/M, codes.
What is CPT code G2211 and how does it affect primary care revenue?
G2211 is a Medicare add-on code that pays for the added complexity of serving as a patient's ongoing, longitudinal point of care, and CMS estimates it qualifies on roughly 90% of primary care E/M claims.
Can G2211 be billed with an Annual Wellness Visit?
Yes. As of the 2025 Medicare Physician Fee Schedule update, G2211 can be billed alongside an Annual Wellness Visit when a separately identifiable E/M service with modifier 25 is also performed.
How much does G2211 typically pay?
The national average Medicare reimbursement for G2211 is approximately $16 per qualifying visit, though the exact amount varies by locality and the applicable conversion factor.
What CPT codes are used for Annual Wellness Visits?
G0438 is used for the initial Annual Wellness Visit, and G0439 is used for subsequent Annual Wellness Visits, both of which are separately payable under Medicare Part B.
Why is E/M coding accuracy especially important for primary care practices?
Because the majority of primary care revenue comes from E/M visit levels, small coding errors compound quickly across a high volume patient panel, and industry data shows up to 19% of E/M visits nationally are undercoded.
What is the difference between 99213 and 99214?
Both are established patient office visit codes, with 99214 representing a higher level of medical decision making or time than 99213, based on documented complexity of the visit.
Do commercial payers reimburse G2211?
G2211 is a Medicare specific HCPCS code, and commercial payers are not obligated to reimburse it. Coverage varies by payer and should be verified before billing G2211 on non-Medicare claims.
Can G2211 be billed for telehealth visits?
Yes. G2211 is on the Medicare telehealth services list and can be billed with eligible office and outpatient E/M visits delivered via real time audio and video telehealth.
What changed with G2211 in 2026?
Starting January 1, 2026, G2211 expanded to home and residence E/M visit codes 99341 through 99350, in addition to the original office and outpatient E/M codes.
How does ClaraRCM help primary care practices capture G2211 revenue?
ClaraRCM checks every qualifying E/M encounter for G2211 eligibility automatically, rather than relying on staff to remember to apply a relatively new add-on code.
